  // ## Parser

  // A recursive descent parser operates by defining functions for all
  // syntactic elements, and recursively calling those, each function
  // advancing the input stream and returning an AST node. Precedence
  // of constructs (for example, the fact that `!x[1]` means `!(x[1])`
  // instead of `(!x)[1]` is handled by the fact that the parser
  // function that parses unary prefix operators is called first, and
  // in turn calls the function that parses `[]` subscripts — that
  // way, it'll receive the node for `x[1]` already parsed, and wraps
  // *that* in the unary operator node.
  //
  // Acorn uses an [operator precedence parser][opp] to handle binary
  // operator precedence, because it is much more compact than using
  // the technique outlined above, which uses different, nesting
  // functions to specify precedence, for all of the ten binary
  // precedence levels that JavaScript defines.

// Acorn: Loose parser
//
// This module provides an alternative parser (`parse_dammit`) that
// exposes that same interface as `parse`, but will try to parse
// anything as JavaScript, repairing syntax error the best it can.
// There are circumstances in which it will raise an error and give
// up, but they are very rare. The resulting AST will be a mostly
// valid JavaScript AST (as per the [Mozilla parser API][api], except
// that:
//
// - Return outside functions is allowed
//
// - Label consistency (no conflicts, break only to existing labels)
//   is not enforced.
//
// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
//   the parser got too confused to return anything meaningful.
//
// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
//
// The expected use for this is to *first* try `acorn.parse`, and only
// if that fails switch to `parse_dammit`. The loose parser might
// parse badly indented code incorrectly, so **don't** use it as
// your default parser.
//
// Quite a lot of acorn.js is duplicated here. The alternative was to
// add a *lot* of extra cruft to that file, making it less readable
// and slower. Copying and editing the code allowed me to make
// invasive changes and simplifications without creating a complicated
// tangle.
